Phylogenetic tree and gene structure of the GA oxidase in plants. a The maximum likelihood tree of 41 species’ GA oxidase genes constructed on 854 deduced full-length peptide amino acid sequences and rooted with homologous sequences of algae. b The sketch map of GA oxidases structure: Exons and introns are indicated by blue boxes and yellow lines, respectively.
